The shell 1 is formed on one side with a radiation window 10 and on the other side with a bladder containing hood 12. The cable ends are connected to the resilient supports 7, 8 of the tube. The air flow may be canalised by means of a second casing concentric with the shell 1-and supported by sleeves 16, 17. The shell 1 may have a ribbed surface and may be supported in the collars of a pivoting fork which may be suspended or slidable on a displaceable column. The edges of the sleeves 16, 17 may fit into the collars of such a fork. Specification 551,895 is referred to.
